Use the hearing to determine if the hydraulic jack system is working properly, usually four listening: one listening to noise.
The method of fault diagnosis of hydraulic jacks is: amenities, logic analysis, special instrument detection, state monitoring, etc.
Electric hydraulic oil pump maintenance precautions
Method of use of electric hydraulic oil pump: When the electric hydraulic oil pump is used, the deflation nut should be opened, open the switch on the press, insert the power supply, and set the quick connector to the fast head applied to the hydraulic instrument.
The electric hydraulic oil pump can be used as a hydraulic pump of various hydraulic instruments. After the electric hydraulic oil pump is equipped with other hydraulic tools, it is possible to make a lifting, pressure type, eluting tube, bending, collections, shear, assembly, disassembly, etc. Reduce labor, improve work efficiency.
Disadvantages of hydraulic transmission: Hydraulic transmissions have the following disadvantages compared to other drives. (1) Strict gear ratio cannot be guaranteed due to leakage and liquid compressibility. (2) Hydraulic transmissions are more sensitive to changes in oil temperature, and should not work at very high and low temperatures. (3) Due to leakage, it is easy to pollute the surrounding environment.
